Microchip PIC16F688-I/SL 8-bit Microcontroller, SOIC-14, 20MHz, 7KB Flash

The Microchip PIC16F688-I/SL is an 8-bit Flash-based microcontroller in a compact 14-pin SOIC-14 surface-mount package, offering 20MHz operation and 7KB of Flash memory.

Overview

Built on nanoWatt technology, this low pin-count PIC microcontroller brings the established mid-range x14 architecture into a space-constrained design. It operates across a wide voltage range of 2.0 to 5.5V and includes on-board EEPROM data memory for reliable non-volatile storage.

Analogue Peripherals

The device supports up to 8 channels of 10-bit Analogue-to-Digital Conversion (ADC) and includes an analogue comparator module with a programmable on-chip voltage reference.

Communications

The Enhanced USART (EUSART) peripheral supports serial communication protocols including RS-232, RS-485 and the LIN bus protocol, suiting industrial and automotive networking applications.

Key Features

• nanoWatt Technology: Designed for low power consumption, supporting extended battery life in portable and remote devices.
• Development Support: MPLAB ICD 2 programming and debugging support, with an optional header adapter.
• System Management: Software-selectable Brown-Out Reset (BOR), power-saving sleep mode, Power-on Reset (POR), and Power-up and Oscillator Start-up Timers (PWRT and OST).
• Watchdog Timer: Low-current watchdog timer (WDT) with an on-chip oscillator for fail-safe operation against code execution errors.
• Industrial Reliability: Extended operating temperature range from -40°C to +85°C, suited to harsh environments.
• Security: Programmable code protection and a multiplexed master clear pin with a weak pull-up.

Summary

Choose the Microchip PIC16F688-I/SL when you require a compact 8-bit microcontroller with analogue inputs, serial communications and low-power operation in a surface-mount package.
